Description
The M52757FP is a semiconductor integrated circuit for the RGB interface. The device features switching signals input
from two types of image sources and outputting the signals to the CRT display, etc. The frequency band of video
signals is 250 MHz, acquiring high-resolution images, and are optimum as an interface IC with high-resolution CRT
display and various new media.
It includes Sync-separator, Video-signal-detector, and Sync-on G detector (SOG-DET.).
Features
• Frequency band width: R.G.B 250 MHz
• Input level: R.G.B 0.7 V
• Video signal-detector
Responsive frequency: to 50 MHz
Input level: 0.7 V
Detected level: 150 mV (Typ.)
(Measure bottom to DET. level)
• Only the G channel is proved with buffer video output.
• It is possible to save the consumption current by stopping current supply to Pin 2, 4, 6, 20, 24, 30, 33, 35 because
SOG-DET can be operated with only V
• Include Sync Separation, Video signal detector, and Sync-on G detector.
